<P><STRONG>Function</STRONG>
<P>
Creates a new generic Group Object.
<P><STRONG>Syntax</STRONG>
<BR>
<TT><STRONG><BR>
&#35;include &lt;dx/dx.h&gt;<BR>
<P><BR>
Group DXNewGroup()<BR>
</STRONG></TT><BR>
<P><STRONG>Functional Details</STRONG>
<P>
A generic Group consists of a
number of members that may optionally be named.  There is no restriction
on the class of Objects in a generic Group and no requirement that the
type of the members be the same.
This is in contrast to the Composite Field,
MultiGrid, and Series subgroups of the class Group, which generally
contain members of class Field and
are typed.
Generic Groups may be explicitly typed using
<TT><STRONG>DXSetGroupType</STRONG></TT> if all
the members are of the same type.
<P>
Named members are added to a Group with <TT><STRONG>DXSetMember</STRONG></TT>.
Unnamed members are added to a Group with
<TT><STRONG>DXSetEnumeratedMember</STRONG></TT>.
<P>
The Group created can be deleted with DXDelete.
See <A HREF="progu023.htm#HDRMEMNG">4.2 , "Memory Management"</A>.
<P><STRONG>Return Value</STRONG>
<P>
Returns the Group or returns <TT><STRONG>NULL</STRONG></TT> and
sets an error code.
